Cup Temperature - Experiment

Questions:
Which cup insulated the best?   I think the Tinfoil cup worked the best.

Which cup worked the worst?    I think that the normal cup had worked the worst.

Which cup is best to hold a hot drink in? I would use the tinfoil cup because if it's newspaper, the paper could get wet and you might need to cool it down.

This is my line graph I did for my Cup Temperature experiment. We had 3 cups, one covered with tinfoil, one covered with newspaper, and one normal cup. Every 3 minutes we had to check the temperature, and see which cup cooled the fastest. We also made up some questions as you can see above.
